When lifting heavy objects at one end only one hydraulic cylinder hydraulic jacks 300 tons temporal heart, they should be placed on heavy hydraulic jacks symmetry axis, and the direction of the long hydraulic jacks and heavy base easily dumped in the same direction. If the heavy end of the use of two hydraulic jacks heart temporal quality hydraulic cylinders, the direction of the base should be slightly splayed symmetrically placed on both sides of the symmetry axis of the weight. Note 1: Do not overload to use 2: jack only on a hard, level surface using 400 tons of hollow hydraulic cylinders, prohibiting several jacks with 3: After heavy lifting, should be timely support bracket weight before maintenance operation 4: Do not attempt to disassemble the jack, so as to avoid the risk of functional failure or produce hollow hydraulic 80.200 tons _ _ Jiayuguan Texas aerospace hydraulic hollow hydraulic cylinders supplied by Dezhou City aerospace hydraulic machinery plant.
